叉车蓄电池以旧换新 电动铲车电瓶安装方法24-4DB280 48V280Ah

电瓶叉车蓄电池以旧换新多少钱？一般更换新的叉车蓄电池建议旧电池交给具备有回收资质的公司，这样可在新叉车电瓶上折扣一定的费用，降低叉车蓄电池更换成本，贝朗斯公司拥有多名技术人员，全国各地可快速配送，提供安装服务。电池的容量一般是指25℃以10小时率放电能放出的容量，对单次放电来说，温度上升会提高放电容量，温度下降会降低放电容量。但对长久使用来说，温度升高会使电池寿命缩短，而低温却能延长电池的使用寿命，这主要是由于蓄电池的工作原理造成的。电动叉车蓄电池的充放电过程是一个化学反应，充放电过程其实就是正负极板氧化-还原反应的过程。温度升高会使正负极板参与化学反应的活性物质增多，温度降低参与反应的活性物质就少，所以就单次放电来说高温有助于提高蓄电池的容量，但长期的高温环境会使板栅的腐蚀加剧，再加上温度升高浮充电流增大、电池脱水等因素，电池的使用寿命会受到很大的影响。实验表明，以25℃为标准，温度每升高10℃，电池寿命就下降一倍，在实际电动叉车使用环境中，有些电动叉车夏天温度能到达五六十摄氏度，这样蓄电池在运行两三年之后容量也就相当于标准容量的十分之一左右，所以温度是造成蓄电池容量下降的主要原因之一。

电动叉车蓄电池以旧换新是很多经销商常规销售手法，不同型号的旧电池费用减免不一样，失效是指新牵引蓄电池未使用就失效报废了。由于极板的种类、制造条件、使用方法有差异，终导致蓄电池失效的原因各异。归纳起来，牵引蓄电池的失效有下述几种情况：牵引蓄电池制造材料中的活性物质组合不合理，极板在化学处理时未达到充放标准；极板贮存环境不良或存放时间过长，密封受损，长期处于空气的氧化之中，致使极板活性物质被老化；在使用过程中维护不当，某一单体长时间处于去电状态，大电流放电时去电单体出现反极电压后，仍未及时给蓄电池维护：如调整电解液密度，加蒸馏水，给蓄电池补充电，导致该单体不可逆硫化而失效。在电动叉车蓄电池的使用过程中，往往是夏季未及时给蓄电池加水，气温高蒸发快导致电解液不足或干枯，使极板露出电解面后受空气而氧化氢脆导致极板硫化而坏死。所以，牵引蓄电池的损失是夏季时期，动力是在夏季时气温高易起动，对牵引蓄电池容量要求高，可是牵引蓄电池在夏季时极板活性物质局部面积形成硫化，冬季时要求牵引蓄电池大电流供电已不可能。如果起动或牵引用牵引蓄电池经充电额容量的70%时，只有报废，更换新的蓄电池了。

How much is battery replacement for battery forklift? General replacement forklift battery new proposal to have the old battery recycling companies, so in the new battery forklift discount certain costs, reduce forklift battery replacement costs, Bei rance company has more than technical staff, the country can fast delivery, provide installation service. The capacity of the battery generally refers to the capacity of 25 DEG C to discharge at 10 hours. For single discharge, the increase of temperature will increase the discharge capacity, and the drop of temperature will decrease the discharge capacity. But for long-term use, the increase in temperature will shorten the life of the battery, while the low temperature can extend the service life of the battery, mainly due to the operation of the battery. The charge discharge process of the electric forklift is a chemical reaction, and the charging and discharging process is the process of oxidation reduction reaction of the positive and negative plate. Active material temperature of the positive and negative plates in chemical reaction temperature increased, decreased the activity of substances involved in the reaction is less, so the single discharge for high temperature is helpful to improve the capacity of the battery, but long-term high-temperature environment will make the grid corrosion intensified, coupled with the temperature increase, the battery charge current dehydration and other factors, the battery life will be greatly affected. The experiment showed that at 25 C for the standard, increasing the temperature of 10 DEG C, the battery life fell twice, in the actual use of electric forklift in some electric forklift summer temperatures can reach fifty or sixty degrees Celsius, so the battery after two or three years of operation capacity is equivalent to the standard capacity of about 1/10, so the temperature is0ne of the main the cause of decline in battery capacity.

Electric forklift battery to replace the old, is a lot of dealers conventional sales practices, different types of old batteries cost remission is not the same, the failure of the new traction battery is not used, it is invalid, scrapped. The reasons for the failure of the battery are different due to the kinds of plates, the manufacturing conditions and the methods of use. To sum up, the traction battery failure has the following several kinds: traction battery manufacturing materials in active substance combination is not reasonable, the plate does not reach the discharge standard in chemical processing; plate storage environment is bad or the storage time is too long, the seal is damaged, air oxidation in a long term, the plate active material is used in the process of aging; in improper maintenance, a single long time in the electric state, high current discharge to electric single anti voltage, not timely for battery maintenance: such as adjusting the electrolyte density, add distilled water to the battery supply electricity, the monomer of irreversible vulcanization and failure. In the process of using battery electric forklift in summer is often not timely to battery water, high temperature evaporation quickly cause electrolyte deficiency or dry, so the plate surface exposed by air oxidation and electrolytic hydrogen embrittlement caused the plate curing and necrosis. So, the loss of traction battery is the summer period, power is in the summer high temperature easy start, for the traction battery capacity requirements, but in the summer when the traction battery plate active material local area formed in the winter for traction battery vulcanization, high current power supply has not been possible. If the traction battery for starting or traction is 70% of the charging capacity, the battery will0nly be scrapped and replaced.
